RP/0/RP0/CPU0:router(config)# router bgp 140
RP/0/RP0/CPU0:router(config-bgp)#
Router Address Family Configuration Mode
The following example shows how to enter router address family configuration mode:
RP/0/RP0/CPU0:router(config)# router bgp 112
RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 multicast
RP/0/RP0/CPU0:router(config-bgp-af)#
Neighbor Configuration Mode
The following example shows how to enter neighbor configuration mode:
RP/0/RP0/CPU0:router(config)# router bgp 140
RP/0/RP0/CPU0:router(config-bgp)# neighbor 10.0.0.1
RP/0/RP0/CPU0:router(config-bgp-nbr)#
Neighbor Address Family Configuration Mode
The following example shows how to enter neighbor address family configuration mode:
RP/0/RP0/CPU0:router(config)# router bgp 112
RP/0/RP0/CPU0:router(config-bgp)# neighbor 10.0.0.1
RP/0/RP0/CPU0:router(config-bgp-nbr)# address-family ipv4 unicast
RP/0/RP0/CPU0:router(config-bgp-nbr-af)#
VRF Configuration Mode
